11 Claims. (Ci. 242-78) This invention relates to dead blocks and more particularly to an apparatus for coiling the finished product of a wire-drawing machine.

In the art of drawing wire, the raw material is passed through a series of dies of successively diminishing diameters, there being a drawing block between each successive pair of dies. The drawing block serves to store the wire between dies and also to determine the amount of back pull and forward pull that exists on the wire as it passes through each die. After the reduction of the Wire in such a series or" dies and drawing blocks, it is desirable to form the wire into coils for ease of transportation and storage, lt is possible, of course, to pass the wire onto a revolving block which is similar to the drawing blocks described above. However, it is necessary, after a coil of wire has been built up on any finishing block, I'aa to cut the wire and remove the coil of wire so built up; with a revolving iinish block the dangers inherent in so cutting and removing the coil are evident. It is undesirable, of course, to stop the machine every time a coil has been produced. The answer to this problem is found in the provision of a so-called dead block; that is to say, the finishing block remains stationary and the wire is fed onto it peripherally by means of a guide member which revolves around the block. It can be seen, then that in such an apparatus the wire will move axially along the block away from the point onto which it is fed and can be cut and removed from the block without difficulty, since the wire and block are stationary to all intents and purposes. Now, for such a dead block to operate in the manner desired, it must have a free end from which the coil may be removed; since this limitation must be met, then only the other end of the block remains for providing the necessary support. The guide member must be positively driven with respect to the dead block, so this means that the wire must enter the system co-axially with the guide member, or else some means, usually very intricate, must be provided for enabling the wire to pass through the driving means at every revolution of the guide member. The entrance of the wire into the system in such a manner leaves only one way of supporting the dead block, i. e., by mounting it rotatably on and coaxially with the guide means. When this is done, a problem still remains as to how the dead block can be kept stationary relative to the floor since the peripheral pull on the wire being coiled tends to rotate the block. One method proposed in the past involves the provision of a counterweight which is designed to set up a torque in the block which balances the torque due to wire tension. The greatest difhculty experienced in the use of such a device is that the torque is not constant due to changes in wire tension and in the distance from the axis of the block of the point to which the Wire is directed; such changes in torque cause the counterweight to oscillate with resultant breakage of the wire. Another solution which has been put forth is that of slotting the dead block and permitting the arms of a turnstile which is ixed relative to the oor to slide successively in the slot,

a coil being removable from the block between successive arms of the turnstile. ln addition to the intricacy of such an apparatus, the dangers inherent in such a method of operation are obvious. The present invention obviates the difiiculties of the prior art in a manner which will be evident from the description which follows.

lt is therefore an outstanding object of the present invention to provide a dead block for the coiling of elongated material which block has no dangerous appurtenances and which permits continuous removal of coiled material therefrom. 1

It is another object of this invention to provide a novel means of preventing the rotation of a dead block relative to the surface to which the machine is attached.

A further object of the instant invention is the provision of a xing means ior a dead finishing block on a wire drawing machine.

Another object of the present invention is the provision of a finishing block. for a continuous wire-drawing machine which permits the removal of wire in bundles or otherwise at any time during the operation of the machine with complete safety to the operator.

Still another object of this invention is the provision of a machine for continuously winding wire on one end of a drum and permitting its removal from the other end in coils or the like without stoppage of the machine.

Generally speaking, the present invention consists of providing magnetic forces between the dead block and a member fixed relative to the door; the wire in rotating about the block as it is fed thereon, is free to pass through the magnetic field which is the only restraining connection between the dead block and the floor. In the preferred embodiment, this is accomplishedby providing the dead block with a radial ange adjacent the end opposite the free end; a restraining member is fastened to the oor and surrounds the dead block adjacent the said tange. The iange and the restraining member are provided with matching magnetic members. The dead block is restrained from rotation relative to the restraining member and the wire, as it moves about the dead block with the guide members, is free 'to move onto the dead block through the space between matching magnetic members.

With these and other objects in view, as will be apparent to those skilled in the art, the invention resides in the combination of parts set forth in the specification and covered by the ciaims appended hereto.

Figure 3 is a vertical sectional view of another embodiment of the instant invention taken on the line 3 3 of Figure 4.

Figure 4 is a front elevation of the apparatus shown in Figure 3.

Referring rst to Figures l and 2, the dead block apparatus, generally designated 1i?, is shown as comprising a main body member 11', a restraining member 12, a block 13, and a spider 1d. The main body member 11 and the restraining member 12 are mounted on a at base 15 which, in turn, is boited to the iioor. The main body member has a generally ooX-iike substructnre 16 which constitutes a support for an integral housing 17. The housing 17 is of generally short, tubular construction and is held with its axis generally parailel to the oor. The restraining member 12 is plate-like in character and has triangular fanges 1f; and 19 extending at right angles to the surface thereof and forming plate.

is arranged perpendicularly to the axis of the housing 17V of the main body member and is provided with a circular aperture 20 which is concentric with said axis.V Generally'spe-aking the upper edge of the restraining member is acir'cular arc and the side edges are vertical and tangential to the arc.

' The housingl? of the body member 11 is, asV Vhas been said, of tubular shape. One end is closed by an integral end member 21 and this member is; provided with anV axial bearing 22 and a seal 23V therefor. ln thek bearingA 22 rides ashaft 24 arranged concentrically withfthe axis of the'housing of the body member. The

shaft 24 extends externally of the housing and is pro-Y vided witli a sheave 25 ymounted on the extending portion.Y The shaft 24 is alsofprovided with an axial bore 32 of small diameter extending throughout its length.

The' shaft extends through the housing to a point adjacent the'end thereof opposite the end member 21'; at

that' point it is provided with an enlarged end 26 which Yis Ybolted to-.the spidery14. The portion of the spider which is so bolted tothe shaft constitutes a cup-like hub 27' which has a closed, Vgenerally cylindrical portion 28 which is supported in the housing 17 by means of a bearing 29. The enlarged end of the shaft is pro- 'vided with an axial recessV 36 which provides clearance between theshaft and the hub for the mounting means for a guide pulley 31. The hub is provided with an axial bore 33 which is of the same size as that throughV the shaft and which is, of course, coaxial therewith. The shaft and the hub are joinedby a plug 34 which has a bore 35 so arrangedrit forms one continuous passage with the bores 32 and 33. The inside of the hub has the guide pulley 31 residing therein and the bore 33 opening therein. The housing 17 is ordinarily providedrwith a pool 36 of lubricating oil and a splash disk-37 mounted on'the shaft 24 to keep Vthe oil distributed over the surfaces within the housing.

. Therhub 27 is provided with an annular flange which extends therefrom,perpendicularly to the axis of the housing.` Bolted to this liange and serving as a cover for the cup-like hub is a mounting plate 38 of generally disk-like shape. Clamped kbetween the said llange and Vthesaid mounting plate by the same Aboltsthat hold them together isV an annular plate 39 which extends perpendicularly to theV axis of the housing 17. Mounted on the annular plate 39 at a point adjacent the outer Vedge, is a bracket 40 which supports guide pulleys 41 and 42.' The guide pulley 41 is situated outwardly of the annular plate and is on the side thereof which faces theihousing 17. The guide pulley 42 is also situated outwa'rdly of the annular plate, but resides on the side there- Yof away from the housing. The pivots of the two guide pulleys are parallel, thus providing that they lie in the same plane. An vadjustable die 43of a well-known type may be mounted on the bracket 40 also. A

i VThe, mounting plate 38 is provided with an axial bore 44 andfin this bore is xedly held a stub shaft 45. The stub shaft has an annular shoulder 46 and is tightly tted in the bore 44 so that it rotates with the mounting The block 13 is pivotally mounted on the outwardly extending stub shaft by means of bearings 47 Yand 48. These bearings are mounted within a tubular inner member 49 constituting part of the block 13. The enclosure between the bearings contains oil and the por- YVil 0 tion of the stub shaft enclosed therein is provided with V- V49 in telescopingrrelation. The inner member 49 and the outer member 50 have annular anges 72 and 73 used'to bolt the two together. VvAn annular Varmature disk 51 is clamped between the two flanges by the same bolts which serve to hold the inner Vand outer members Vtogether and forms a flange 74 which extends generally Il Y perpendicularly to the axis of the shaft 45. AdjacentY the edge of the armature disk 51 and on the side thereof facing the housing 17 is fastened a counterweight 69..

On the side of the armature disk 51 facing away from the housing 17 Yare fastened a series of pole pieces 52', whose characteristics will be described vmore fully hereinafter, In the preferred embodiment there are six, equally-spaced pole pieces.

Returning again to the restraining member 12, the block 13 extends through the aperture 20 and Vthe restraining member and the armature disk are parallel and spaced from each other. Exactly opposed to each pole piece 52 is a magnet 53, to be described more fully hereinafter. The faces of the pole pieces and the magnets are separated by a small distance and are covered by brass guide sheets 54 and 55, respectively. The guide sheets are of annular shape and are bent awayV from each other at their outerA peripheries; they are fastened safety.l The guard 56 comprises a front panel 57 which. iswelded or otherwise attached tothe restraining mem- 7 ber 12 and a movable portion 58 which is mounted on rollers 59 riding on tracks 60 for movement to a rearwardY position, shown in dotted lines, when access is desired to the mechanism of the apparatus.

A bore 61 is provided in the hub 27, the axis of vsaid bore being at right angles to the axis of the housing 17. The pulley 31 which is mounted within Vthe hub is situated so that the axes of the bores 33 and 61 are tangential to its outer periphery.' A sheath 62 .extends from bore to bore and passes around the pulley; the sheath is of tubular construction and has material removed on the inside Yof the curve formed as theY sheathY of theV shaft 24 in alignment with the bore 32 which Y passes axially therethrough. The oil reservoirs inV the' housing 17 'and the inner member 49 are supplied with Y The pole pieces 52 are formed of a magnetizable ma' terial such as soft iron and are of ygenerally rectangular They are arranged around the outer edge of theV shape. armature disk 51 with their longest dimension extending tangentially thereto. The magnetsSS are of the permanent type formed of a well-known nickel-cobalt-aluminum alloy and, in the preferred embodiment, are of horseshoe shape. The magnets are fastened to the restraining mem-- ber proper with their poles adjacent the pole pieces.52`.

A magnet strap 71 may extendacross the'poles of the magnet to assist in the mounting.

-Inthey operation of the apparatus' describedrabove, the

wire which is to. be coiled on thel block is fed into the bore 32 of the shaft 24. In most cases, `only one of the dies 43` or 63 are used at any one time. VIfthe die 63 is used, the'wire must be threaded through it first. The wire is pushed into the bore 32, passes through the bore 35 of the Vplug 34, and thenvpasses through the bore 33V in the hub 28. The wire, still being pushed by the operator, passes from the bore 33 into the sheath 62, around the pulley 31, and is guided by the sheath into the bore 61. The wire is'then passed over the pulley 41, and then over the pulley 42. If the die 43is used, the wire is then passed through that die.l ThenV the Ywire is passed between the guide sheets 54 and 55 to the outer member 50 of the block 13 where it is fastened. The apparatus is then ready Vfor coiling.

The shaft 24 is driven by means of amotor-driven belt passingaround the sheave 25; Since the shaft'24 is b'o'ltedV to the spider 14, the latter also revolves about the axis of the shaft. When the spider 14 revolves, the stub shaft also revolves, Since the free end of the wire is fixed to the block 13 and the spider carries the pulleys 41 and 42 around with it, the wire is Wound on the block. As the wire is wound on the block it is under tension and exerts a tangential force on the periphery of the block. This tends to turn the block. Now the block is mounted on the stub shaft 45 which, as has been said, revolves with the spider; however, the bearings 47 and 48 between the stub shaft and the block permit the block to be independent of the stub shaft revolution. Nevertheless, since the block has a torque exerted upon it by the Wire, it tends to turn in the same direction that the spider is revolving. In the present invention, however, the block is restrained from partaking of such a revolution by the fact that it is furnished with the pole pieces 52 which are restrained from movement from their positions within the lines 0f force of the magnets 53. The guide sheets 54 and 55 provide for the wire passing smoothly between the pole pieces and the magnets and prevent the wire from catching on edges of these parts. The wire is, of course, magnetized slightly as it passes through the lines of force of the magnets; however, it has been found that the amount of magnetization is so slight as to have no effect on the commercial value of the wire. The ange on the outer member of the block 13 is formed with a smooth inclined surface and the apparatus is arranged so that the wire is fed onto this surface and feeds down the ange onto the cylindrical surface of the outer member. From there the wire is progressively pushed outwardly toward the free end of the block by the pressure of successive layers of wire being introduced at the flange end of the block. The forces exerted on the block by the wire may move it slightly so that the pole pieces are not exactly aligned with the magnets, but the magnet forces prevent this from taking place more than a limited extent The coiled wire passes from the outer member 50 ont@ the extension 66 Where it is gathered into bundles of the desired size and is cut to remove the bundle. There is no necessity for the wire being reattached to the block after being so cut because the friction forces between the remaining coiled wire and the block surface are great enough to permit considerable tension in the wire as it feeds onto the block without slippage of the wire already accumulated on the block. The guard 56, which was removed for the initial threading of the wire through the machine, is replaced before the apparatus is put in operanon.

Referring next to Figures 3 and 4 wherein is shown another embodiment of the invention, the dead block apparatus, generally designated 110, is shown as comprising a main body member 111, a restraining member 112, a block 113, and a spider 114. The main body member 111 and the restraining member 112 are mounted on the floor. The main body member has a generally box-like substructure 116 which constitutes a support for an integral housing 117. The housing 117 is of generally short, tubular construction and is held with its axis generally parallel to 4the floor. 'Ihe restraining member 112 is plate-like in character and has triangular anges 11S and 119 extending at right angles to the surface thereof and forming legs in the lower portion. The restraining member proper is arranged perpendicularly to the axis of the housing 117 of the main body member and is provided with a circular aperture 120 which is concentric with said axis. Generally speaking, the upper edge of the restraining member is a circular arc and the side edges are vertical and tangential to the arc.

The housing 117 of the body member 111 is, as has been said, of tubular shape. One end is closed by an integral end member 121 and this member is provided with a bearing 122 and seal 123 therefor. In the bearing 122 rides a shaft 124 arranged concentrically with the axis of the housing of the main body member. rhe shaft 124 extends externally of the housing and is provided with a sheave 125 mounted on the extending portion. The shaft 124 is also provided with an axial bore 132 of small diameter extending all the way therethrough. The shaft extends through the housing to a point adjacent the end thereof opposite the end member 121; at that point it is provided with an enlarged end 126 which is bolted t0 the spider 114.. rlhe portion of the spider which is so bolted to the shaft consists of a cup-like hub 127 which has a closed, generally cylindrical portion 128 which is supported in the housing 117 by means of a bearing 129. The enlarged end of the shaft is provided with an axial recess 13 which provides clearance between the shaft and the hub for the mounting means for a guide pulley 31. The hub is provided with an axial bore 133 which is of the same size as that through the shaft, which is coaxial therewith. The shaft and the hub are joined by a plug 134 which has a bore 13S so arranged that the three bores form one continuous passage. The inside of the hub has the guide pulley 131 residing therein and the bore 133 opening therein. The housing 117 is ordinarily provided with a pool 136 of lubricating oil and a splash disk 137 mounted on the shaft Z4 to keep the oil distributed over the surfaces within the housing.

The hub 127 is provided with an annular harige which extends therefrom perpendicularly to the axis of the housing. Bolted to this flange and serving as a cover for the cup-like hub is a mounting plate 13S of generally disklike shape. Clamped between the said flange and the said mounting plate by the same bolts that hold them together is an annular plate 139 which is arranged perpendicularly to the axis of the housing 117. Mounted on the annular plate 139 at a point adjacent the outer edge is a bracket 14% which supports guide pulleys 141 and 142. The guide pulley 141 is situated outwardly of the annular plate and is on the side thereof which faces the housing 117. The guide pulley 1-'l2 is also situated outwardly of the annular plate, but resides on the side thereof away from the housing. The pivots of the two guide pulleys are parallel, thus providing that they lie in the same plane. An adjustable die 143 of a well-known type may be mounted on the bracket 144i also.

The mounting plate 13S is provided with an axial bore 144 and in this bore is ilxedly held a stub shaft 145. The stub shaft has an annular shoulder 146 and is lixed in lthe bore 144 so that it rotates with the mounting plate.

The block 133 is pivotally mounted on the outwardly extending stub shaft by means of bearings 147 and 143. These bearings are mounted in the inner end surfaces of an inner member 149 constituting part of the block 113. The enclosure between the bearings contains oil and the portion of the stub shaft enclosed therein is provided with an oiling disk. Proper seals are provided externally of the bearings. The block 113 further comprises an outer member 156 which lits over the tubular inner member 149 in telescoping relation. The inner member 149 and the outer member 15G each have an annular ange which is used to bolt the two together. An annular armature disk 151 is clamped between the two flanges by the same bolts which serve to hold the inner and outer members together and forms a ange 173 which extends generally perpendicularly to the axis of the shaft 145. Adjacent the edge of the armature disk 151 and on the side thereof facing the housing 117 is fastened a counterweight 169. On the side of the armature disk 151 facing away from the housing 117 are fastened a series of outer pole pieces 152 and a series of inner pole pieces 157, similar to the pole pieces 52 described in the rst embodiment of this invention. In the preferred embodiment there are six pole pieces in each series, grouped in three at diametrically opposite edges of the armature disk.

Returning to the restraining member 112, the block 113 extends through the aperture 120 and the restraining member and the armature disk are parallel and spaced from each other. Exactly opposed to each pole piece 152 or 157 is a magnet 153 or 158, respectively, similary in y nature to the magnets 53 described with relation to the first embodiment of the invention. The faces of the pole spectively. The guide sheets are of annular shape andare bent away fromy each other at their outer peripheries; they are fastened by welding or otherwise to the faces of their respective pole pieces or magnets.

A guard 156 is provided which extends around the moving parts, particularly the spider 114, for reasons of safety. LYIn this embodiment the restraining memberllZ constitutesY the forward Wall of the enclosure for the moving parts and the guard 156 tits closely therearoundf V'lhe guard is mounted onv rollers 159 which ride on tracks 160 for movement to a rearward position, `shown in dottedlines, when access is desired to the mechanism of the apparatus'. Y

Y A bore. 16 1 is provided in thehub 27, the axis of the said bore being at right angles to the axis of the housing 117. The pulley 131 which is mounted within the hub Vis situated so that the axes of the bores 133 and 161 are pulley; the sheath is of tubular construction and has matep 'rial removed fromV the inside of the curve formed as the Table A Y Preset angle of dead block, degrees 10 15 20 25 Torque from couuterweight, ft. lbs 50 75 99 123 Die pull resisted by cwt. in lbs 75 112 148 183 No; 0f small magnets to hold ewt; 3 4 5 6 Torque from magnets, it. s. 66- 88 110- 132 Dlepull resisted by magnets, lbs 99y 132 165 198 Max. die pull from cornhination 174 244 313 381 While certain novel features of the invention have been shown and described and are pointed out Vthe annexed claims, it will be understood that various omissions, sub- Y stitutions and changes .in the forms and details of the device illustrated and in its operation may be made by those skilled in the art without departing Yfrom the spiritV of the invention.V

The invention yhaving been thus described, what is l claimed asl new and desired to secure by Letters Patent is:

l. Apparatus for coiling wire, comprising: a main body t member, a spider rotatably mounted on said main body member, a block rotatably mounted on said spider, a restraining memberradjacent said block, 'and magnetic means associated with said block and said restraining member to restrain their rotation relative to each other.

sheath passes around the pulley so that the tube opening formed by pulley. l

Y A 'tixed die 163 may be fastened to the rearward end of the shaft 124 in alignment with the bore 132 which passes axially therethrough. The oil reservoirs in the such removal of material is closed bythe Vhousing 117 and the inner member 149 are supplied with oil level indicator gages` 164 and 165 respectively. An extension 166 is fastened to the free end of the block 113 and has several posts 167 joined at their outer ends by a tie plate 168.

As in the case of the embodiment of Figure l, the pole pieces 152 and 157 are formed of a magnetizable mate- Vrial such as soft iron and are of generally rectangular shape. However, the inner pole pieces 157 are smaller than the outer pole pieces 152so that each set of inner and outer pole pieces lies roughly along a sector of the armature disk. The magnets 153 and 158 are of similar material to those of the previous embodiment, but the inner magnets 158 are smaller than the outer magnets 153 and they are arranged in the same way as'the pole pieces, i.V e., the long dimensions are perpendicular toV radii of the disk andthe poles of the horseshoe Vlie opposite the ends of the respective pole pieces.

Y In the present embodiment, a multi-roll Wire straightener Y V170 of a well-known type is fastened to the side of the annular plate 139 of theY spider V114 on the side thereof facing the housing 1177back-to-back with the bracket 140'. Furthermore, a similar wire-straightener 171 may Vbe mounted on the annular plate on the side facing the block 113, but diametrically opposite edge from the bracket 140. Y

@The operation of this embodiment is similar to that of the embodiment illustrated in Figure l,V except that, when the wireV straightener 170 is used, the wire passes through that member as it goes from the bore 161 to the pulley 141'. When the wire straightener 170 is used, the wire passes through that member as it goes from the pulley 142 orV theY die 143 to the block 113. Magnet straps 171 and 172 may be provided to assist in fastening the magnet Yto the restraining member proper. and also to lprovide a iiow path for the lines of force between poles.

As a practical matter, of course, the number and size of the magnets must be chosen to fit the particular operating conditions. The table given below gives some indication of the magnitudes of the factors involved in the design of a dead block consistent with the present invention:
